A solid power transmission shaft of length 2 m and diameter 75 mm is required to transmit 600 kW at a speed of 2500 rpm. Determine the maximum shear stress in the shaft and the factor of safety in operation if the ultimate shear stress in the material is 350 MPa. Determine also the angle of twist in degrees along the length of the shaft when transmitting this power. The shear modulus of the shaft material is 85 GPa
